new UX

Hi Piour,

  I improved the UX of Cozy Feeds. The design is less appealing than before but the content is better displayed. Here are my modifications: 

* I put the option buttons on the left. This way you don't need to scroll down to read your feeds. 
* In the same spirit I changed icons for more discrete ones, so the user can focus on the link list and the feed list.
* The content part is limited to 800px to improve readiness.
* I made activable things (buttons and links) look the same way, to bring more coherence.
* I added some responsive features, but it's a little bit dirty. 
* I kept your background and text colors but I changed the link colors.

I tried to only modify layout and styles, I didn't change any other features. Tell me if I broke something in your feed reading flow, because that was not intentional.

The only thing that is still weird, is that when you connect, no feeds are loaded by default. So the app feels a little bit empty. What would you suggest me to put in the link list to make things smoother?

You can try this design by installing the feed app from this repository.
